The military hopes to remove stigma associated with
PTSD — by replacing "disorder" with the
word "injury"— which could encourage troops, and even civilians
who suffer from it, to seek treatment instead of bottling it up
out of shame.

To put that into context, the events of 9/11 and the start of the
Afghan and Iraq wars have all occurred since the manual was last
revised. In this recent time span, the term "PTSD" has
often cropped up negatively in the public sphere whenever a
service member or veteran commits an inexplicable crime, even
though the disorder may not be the cause whatsoever.
Frustratingly, this leads to PTSD developing an unwarranted bad
rap.

High-level Pentagon officials have previously tried
shortening the label to just Post-Traumatic Stress or PTS. But
without a firm designation as a "disease, disorder or injury" the
medical community is cautious about picking up the shortened
label due to "concerns that insurers and government
bureaucrats would not be willing to pay for a condition that
wasn’t explicitly labeled," finds Jaffe.

So the proposed alternative of Post-Traumatic Stress Injury came
about. Supporters of the switch point out that the illness is
caused by an external force, much like how an injury is afflicted
upon someone. And "injury" suggests that it can be healed. That
shred of optimism could outweigh the stigma, prompting sufferers
to accept medical help. But the change could have inadvertent
consequences:

...A shift to “injury” could make it harder for service
members to collect permanent-disability payments for their
condition from the government, some experts warned...: “This
change is about medicine, but it is also about compensation. We
are talking about hundreds of millions of dollars.”

While a name change may encourage people to seek treatment
without fear of humiliation, those very same people will hit a
devastating wall if their disability benefits don't cover an
illness that's missing a word — a cruel irony that highlights the
importance of making level-headed decisions about this
issue.
